Data diperoleh di SMPN 1 Bolo Kabupaten Bima NTB dengan subjek penelitian 100 siswa dan 4 guru matematika. Instrumen pengumpul data berupa lembar observasi, kamera/alat perekam, pedoman wawancara, angket dan skala sikap. Metode penelitian yang digunakan adalah metode campuran dengan desain pengembangan instrumen afektif mengacu Mardapi. Analisis data menggunakan analisis data kualitatif menggunakan triangulasi sumber dan teknik, validitas, daya beda butir, reliabilitas dan analisis faktor ekploratori. Hasil penelitian menunjukkan dari validasi ahli, 50 butir instrumen awal layak diujicobakan ke skala kecil dengan 27 butir berkategori cukup memadai dan 23 butir berkategori memadai. Hasil uji coba skala kecil, terdapat 32 butir yang berkategori valid dan instrumen reliabel dengan α = 0,85. Setelah instrumen diperbaiki, instrumen digunakan untuk uji coba skala luas dengan subjek 100 siswa dan hasilnya instrumen reliabel dengan rxx=0,73 serta instrumen mampu mengungkap variabel sikap siswa yang diukur sebesar 67,53% dengan jumlah komponen yang terbentuk sebanyak tiga faktor yaitu Jujur, Interaksi lingkungan dan Serius.

The results of the small scale test there are 32 items valid category and reliability instrument with α = 0.85. After the instrument repair, instruments used to test large-scale with the subject of 100 students and as a result the instrument reliability with rxx=0.73 obligation and able to reveal the variables measured students attitude of 67,53% with a number of components that are formed as many as three factors namely honest, environmental interaction and serious.]]>
